Hi! I pretty much don't understand this problem that was presented on my Statistics class 23.In one Introductory Statistics class, the probability that a student will pass the first test is 0.55. If thestudent passed the first test, the probability that they will pass the second test is 0.75. If they failed the first test,the probability that they will fail the second test is 0.7.a. Compute the probability that a student will fail the second test, given they passed the first test.b. Find the probability a randomly selected student will fail both tests.c. Find the probability that a randomly selected student will pass both tests.d. Find the probability that a randomly selected student will fail at least one of the tests.

Hi, I want to know two answers for my statistics class, the first question is how to find the relative risk for receiving a parking ticket for students who commuted by car and those who did not? The second question is to find the risk of having ever received a parking ticket for students who commuted by car? If you could please help, I am struggling a lot with these homework questions! The contingency table is below. In a survey for a statistics class project, students in the class were asked whether they commute to school by car (Yes or No) and whether they had ever received a parking ticket (Yes or No). Of the 23 students who commuted to school by car, 19 had received a parking ticket. Of the 25 students who did not commute to school by car, 7 had received a parking ticket. Here is a contingency table for these data. Received parking ticket? Yes No Total Commute 19 4 23 Doesn’t commute 7 18 25 Total 26 22 48

A) We have just conducted a study examining how much math anxiety students experience after taking a statistics class. We want to know if students on average are reporting low (1) or high (7) levels of math anxiety. To do that, we want to compare the math anxiety levels of the students after they have taken a statistics course to the average population math anxiety. We believe that the students on average will have a level of math anxiety that differs from the population.
